Radboud Chemists Innovate with Robots for Bio-Based Material Transition

Researchers at Radboud University are pioneering the shift from fossil fuel-based products to sustainable bio-based materials, utilizing robots and artificial intelligence to expedite this process. This initiative is part of the university’s broader Big Chemistry program, which aims to address the urgent need for eco-friendly alternatives to conventional chemical products, including medicines, plastics, and paints.

The transition to bio-based materials is a complex challenge. Wilhelm Huck, a professor of physical-organic chemistry at Radboud University, emphasizes the need for a thorough understanding of the molecular behavior of these materials. He explains, “You don’t want to optimize the properties of a single molecule, but of a mixture.” This approach requires extensive data on how different raw materials interact at the molecular level, which is where robotics and AI come into play.

Understanding Molecular Interactions

Chemistry often involves unpredictable interactions among molecules. Huck illustrates this by comparing it to the dissolution of sugar in water. While the behavior of one sugar cube is predictable, combining multiple cubes does not necessarily yield a straightforward outcome. The number of potential interactions among raw materials can quickly escalate into the hundreds of millions, particularly when considering the vast array of components available for products like cleaning agents and cosmetics.

To tackle this complexity, Radboud researchers are employing advanced models that can predict the properties of mixtures. The team is collecting data through experimental research, which will be used to train these models. This data-driven approach aims to facilitate a more efficient transition to bio-based materials without compromising product quality.

Collaborative Projects for Sustainable Solutions

This autumn, three projects funded by the National Growth Fund will explore bio-based materials specifically for paints, soaps, and polymers. Huck leads one of these initiatives alongside researchers Mathijs Mabesoone and Peter Korevaar. Each project involves partnerships with industry leaders to investigate the properties of bio-based raw materials.

Korevaar is collaborating with Van Wijhe Verf to develop paints that maintain waterproof qualities while transitioning to bio-based ingredients. He notes that paints must meet several critical requirements, including stability and washability. “If you try to design that based on new, bio-based ingredients, you need a lot of experimental data,” he says.

Mabesoone’s project focuses on soaps in conjunction with Croda International. His research aims to understand how mixtures of soaps can exhibit varying cleaning capacities, sometimes at significantly lower concentrations than expected. The goal is to compile a comprehensive database of measurement points that will enhance predictive modeling.

The third project addresses the development of bio-based polymers in collaboration with TNO and Van Loon Chemical Innovations (VLCI). Huck points out that many polymers lack sufficient data for theoretical calculations, making this research vital for future developments.

Robots at the Forefront of Data Collection

A key component of these projects is the use of robotics to generate extensive data. The researchers currently utilize small robots that can conduct continuous measurements and experiments. A larger robot lab is set to open at Noviotech Campus in Nijmegen by the autumn of 2026.

Mabesoone describes the functionality of these robots, stating, “You supply such a robot with a few samples of basic solutions, and then you put it to work testing, mixing, and measuring.” This automated process allows for the efficient collection of data that would be impossible to gather manually, enabling faster advancements in material science.

Implications for Consumers

As this research progresses, consumers may notice changes in the products they use. Huck suggests that without such innovations, certain items could become unavailable due to regulatory restrictions on harmful substances. However, if the transition is successful, consumers can expect to see improved bio-based products that maintain high standards of quality while being more environmentally friendly.

In conclusion, the work being done at Radboud University reflects a significant step towards sustainable materials in the chemical industry. Through the integration of robotics and AI, researchers are poised to discover new properties and formulations that could reshape the future of everyday products.
